Abstract

The invention discloses a high-bending-degree wide-color-gamut ceramic curved surface rock plate and a preparation method and application thereof. The thickness of the curved surface rock plate is 3-6 mm, the curvature radius is larger than or equal to 100 mm, and the arc center angle is 0-180 DEG C. The curved surface rock plate comprises a glaze layer, and the glaze layer comprises a ground glaze layer and a cover glaze layer arranged on the upper portion of the ground glaze layer. The ground glaze layer is prepared from the following raw materials in parts by weight: 81-90 parts of EN-1 frit, 8-12 parts of kaolin, 2-7 parts of quartz, 0.3-0.5 part of sodium tripolyphosphate and 0.15-0.22 part of sodium carboxymethyl cellulose; the cover glaze layer is prepared from the following raw materials in parts by weight: 30-45 parts of 7 # transparent frit, 8 parts of kaolin, 0-7 parts of quartz, 0-40 parts of albite, 0-15 parts of potassium feldspar, 0-5 parts of dolomite, 0-5 parts of calcite, 0-6 parts of barium carbonate, 0.3-0.5 part of sodium tripolyphosphate and 0.15-0.22 part of sodium carboxymethyl cellulose. According to the ground glaze formula adopted by the curved surface rock plate, after hot bending and re-burning, glaze cracks of the bottom surface glaze are not generated, the phenomena of matt recrystallization and glaze layer devitrification are avoided, and the color gamut range is widened.

Description

technical field [0001] The invention relates to the field of ceramic rock slabs, in particular to a ceramic curved rock slab with high curvature and wide color gamut and a preparation method thereof. Background technique [0002] In recent years, with the improvement of people's requirements for the beauty of buildings, in order to improve the competitiveness of products, various manufacturers have invariably focused more on the aesthetic appearance of products, using various curved surfaces such as natural stone or artificial stone. The use of materials to decorate buildings is increasing, and the amount is relatively large. [0003] Using natural stone to process curved surface products requires a large amount of processing and low stone utilization, resulting in high production costs for natural stone curved surface products, and the decorative surface of natural stone has a large color difference. Marble is generally sedimentary and metamorphic rock, the main component ...
